Carbon tetrachloride or carbon tet is a non-flammable, dense, colorless liquid which was often used as a cleaning agent in the mid 1900s, but was phased out due to safety and environmental concerns. High exposure can affect the central nervous system and cause damage to the liver and kidneys. Prolonged exposure can be fatal.

Overview of functionality of an IBM typewriter.

To add longevity to one's carbon papers they should be rotated both top to bottom and front to back within one's packs.

Use plastic type cleaner, meant for cleaning type slugs, to clean the excess ink from a typewriter. Form it into a point and press it to the letter to erase several times. Then erase with eraser shield and eraser.

To type to the very bottom of the page, particularly with a carbon pack, to prevent slippage at the bottom, insert a "trailer sheet" about halfway down the first page. Insert it at the back of the pack just behind the original and between the first carbon sheet.

For typing small sheets of paper (index cards) fold a pleat into a regular sheet of paper and use the lip to hold the smaller sheet you're typing on.

To more quickly type envelopes, do the first then reverse the platen so that only about an inch of the top of the envelope is visible. Then insert the next envelope behind the first and continue reversing the platen. This will allow the finished envelopes to stack at the paper table and speed the threading and typing of envelopes in rapid succession.

Use of the divots on the typing guide for making horizontal or vertical lines while moving the carriage or rotating the platen respectively.

Fossilized Masking Tape Removed Cleaned from Typewriter Body by [[Phoenix Typewriter]]

The paint on the metal of the SMC 6 series typewriters will generally stand up well to lacquer thinner and along with scratching can be used to remove the old residual masking tape often found on these typewriters.

WD-40, gun bore cleaner, and Simple Green generally don't do much to this sort of tape residue.
